libavutil/common.h is a public header that provides generic math functions whereas libavutil/intmath.h is a private header that contains plattform-specific optimized versions of said math functions. common.h includes intmath.h (when building the FFmpeg libraries) so that the optimized versions are used for them. This interdependency sometimes causes trouble: intmath.h once contained an inlined ff_sqrt function that relied upon av_log2_16bit. In case there was no optimized logarithm available on this plattform, intmath.h needed to include common.h to get the generic implementation and this has been done after the optimized versions (if any) have been provided so that common.h used the optimized versions; it also needed to be done before ff_sqrt. Yet when intmath.h was included from common.h and if an ordinary inclusion guard was used by common.h, the #include "common.h" in intmath.h was a no-op and therefore av_log2_16bit was still unknown at the end of intmath.h (and also in ff_sqrt) if no optimized version was available.
